[Frontier Letter] Simulation study of atmosphere–ionosphere variations driven by the eruption of Hunga Tonga-Hunga Ha’apai on 15 January 2022
The volcanic eruption of Hunga Tonga-Hunga Ha'apai on 15 January 2022 caused severe disturbances in the atmosphere and the ionosphere. In this event, it is expected that atmospheric compressibility played an important role in the atmosphere-ionosphere disturbances. However, phenomena associated with compressibility of the atmosphere have not been fully investigated. We used an axisymmetric three-dimensional nonhydrostatic atmospheric model and the whole atmosphere-ionosphere model GAIA to study the phenomena related to compressibility. We found that our simulation can elucidate various kinds of disturbances caused by atmospheric compressibility, such as shock waves and acoustic resonant oscillations of the atmosphere and the ionosphere.
